Tons of people feel that X racism is worse than Y racism, and it's ridiculous to say that they are all irrational people. The reality is that no two things are perfectly equivalent, even if they are both terrible things that should both be eradicated. We should castigate all forms of racism, but that is not at odds with the reality that it is at least a legitimate opinion to claim that the practical consequences of anti-black racism, at least in the English-speaking world, are apparently worse than the practical consequences of anti-white racism.
